Spikekill 1.0 - Released

[Voiper99]

I've just got a couple of questions. What is the difference between using this plugin and setting a hard limit on the graph size (the max limit?) Is it because you may want to allow the data to reach that level on occasion but some times the data may reach that level due to a spike?

My other question is, is it possible to have the plugin run every time a poll is done?

Thanks!

It's essentially a way to correct for a misbehaving data point.

Relative to your other question:

Code: Select all

find <path_cacti>/rra -name \*.rrd -exec php -q spikekill.php ... {} \;

Done.

Thanks for the quick reply Witness. So with that command that you gave me, I assume that I'd need to put that in a cron job along with Cacti's poller?

[TheWitness]

Of course. Make sure you know what you are doing though...

lol that's what I'm worried about. My knowledge of cron is not the best so I do not know if it is possible to ensure that one job runs before the other, but if there isn't, I assume it would not be a good thing if Spike Killer ran while the poller was running at the same time?

It would be better to run as a small plugin directly after the poller runs.

As risk of sounding annoying (which I fear I did long ago), how do I do that?

Hello,

(Not sure if I should open a new thread or continue here... just let me know.)

I've just upgraded two cacti servers to 0.8.7g (official source) + PIA 2.8 + last patches released on July 27th + rrdtool 1.4 on Debian Lenny/Squeeze and KillSpike doesn't work anymore. It seems it doesn't find RRDtool :



Does someone have it working correctly with RRDtool 1.4 ?

Thx

=> Issue solved using the very latest version aka v1.1 not official (?)...

@Voiper99

You probably shouldn't be running this type of thing out of cron. If you have a graph that is constantly being littered with spikes, you should set a maximum value on the data source which the graph relies upon. This way the errant data is never even captured by RRD. This is more for those of us who *forgot* to set a logical maximum on a data source and have to go back and fix it!!

I guess I should make it. I'm loosing touch There are now too many plugins to manage. Not only the open, but the less open ones.

Hello,

Is there a way to provide spikekiller custom settings ? They are spikes, I am not able to flatten !

For ex. in Cacti global config file ?

Code: Select all

$spikekill_method = 1;
$spikekill_number = 10;
$spikekill_deviations = 10;
$spikekill_percent = 400;
$spikekill_outliers = 5;

[TheWitness]

The cli is much more versitile. It not on my list of things to do right now to make any enhancements. But if log an RFC in the bug database i will eventually get to it.

For spikekill i have this settings

spikekill_settings.jpg (41.24 KiB) Viewed 6823 times

and this results

spikekill_error.jpg (106 KiB) Viewed 6823 times

i have \rra\BCK\ directory and write permission on it but still this error. Perhaps the path is not right despite it being green?

[TheWitness]

Use the full path and not just BAK.
